Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more particularly to a packaging device. Background Technology

[0002] Tea packaging equipment is a device that quantitatively packages a large batch of tea leaves according to weight requirements. It can be used in conjunction with packaging machines to achieve fully automated quantitative packaging, or with pressing equipment to achieve fully automated quantitative pressing. The tea packaging equipment includes a feeding device, a weighing device, and a discharging device. The feeding device conveys the tea leaves to the weighing device, which uses a weight sensor to weigh and quantify the tea leaves. The discharging device sends the weighed and quantified tea leaves to the next process step. A vibrating plate is installed between the feeding and weighing devices to gradually supply tea.

[0003] Chinese patent CN214608169U discloses a tea packaging device, including a box (1), with a hopper (2) fixedly connected to the upper end of the box (1). A mounting base (4) is installed inside the hopper (2). A weighing hopper (17), a feeding hopper (8), and a vibrating plate (3) are installed on the mounting base (4). A vibrating plate (5) is installed at the upper end of the mounting base (4). A connecting column (7) is fixedly connected to the mounting base (4), and there are three connecting columns (7). All three connecting columns (7) pass through the vibrating plate (5) and are slidably connected to the vibrating plate (5). A feeding tray (6) is fixedly connected to the upper end of the three connecting columns (7). An operating table (13) is fixedly connected inside the box (1). A heat sealing machine (14) is installed on one side of the surface of the operating table (13), and a packaging bag (15) is placed on the other side of the surface of the operating table (13). The tea leaves to be packaged are poured onto the feeding tray, where they fall onto the vibrating plate and then disperse onto the linear vibrating plate. After passing through the feeding hopper, they are weighed in the weighing hopper and then fall into the collecting hopper. The tea leaves are then packaged by the limiting tube, packaging bag, and heat sealing machine. By reducing manual weighing of the tea leaves, the labor force can be effectively reduced, and by using machines to weigh the tea leaves, the work efficiency of tea weighing and packaging can be effectively improved.

[0004] The general movement path of the tea leaves in this patent is as follows: feeding tray → vibrating plate → linear vibrating plate → weighing hopper. All the tea leaves in the weighing hopper come from the linear vibrating plate. If the vibration frequency of the linear vibrating plate is too fast, the amount of tea leaves entering the weighing hopper will be too large, which may easily lead to an overload of tea leaves in the weighing hopper. If the vibration frequency of the linear vibrating plate is too slow, the weighing time of the tea leaves in the weighing hopper will be too long, resulting in low efficiency. Summary of the Invention

[0005] Therefore, a packaging device is needed to solve the problem that all the tea in the weighing hopper comes from the linear vibrating plate. If the vibration frequency of the linear vibrating plate is too fast, the amount of tea entering the weighing hopper will be too large, which may easily lead to an overload of tea in the weighing hopper. If the vibration frequency of the linear vibrating plate is too slow, the weighing time of the tea in the weighing hopper will be too long, resulting in low efficiency.

[0006] To achieve the above objectives, this embodiment provides a dispensing device, comprising:

[0007] frame;

[0008] The feeding device mounted on the frame includes a hopper and a screw conveyor mechanism. The hopper includes a feeding chamber with an inlet and an outlet. The screw conveyor mechanism is located in the feeding chamber.

[0009] The vibratory plate is mounted on the frame and positioned below the discharge port. The vibratory plate has an inlet section and an outlet section, and the inlet section is used to receive the material coming out of the discharge port.

[0010] The weighing device is mounted on the frame and includes a feeding section and a discharging section. The feeding section is located below the discharging port and the output section. The feeding section is used to receive the material coming out of the discharging port and the output section, and the discharging section is used to output the weighed material.

[0011] Furthermore, the weighing device includes a housing, a weight sensor, and an opening and closing mechanism. The housing is provided with a feeding section and a discharging section that are connected to each other. The weight sensor is located at the bottom of the housing and is used to detect the weight of the material. The opening and closing mechanism is located on the housing and between the feeding section and the discharging section, and is used to collect or discharge the material.

[0012] Furthermore, the opening and closing mechanism includes a motor, a cam, and an opening and closing door. The opening and closing door is rotatably mounted on the outer wall of the housing and located between the feeding section and the discharging section. A guide rod is provided on the outer wall of the opening and closing door. The motor and the cam are mounted on the outer wall of the housing. The motor and the cam are connected by a drive, and the cam and the guide rod are slidably connected.

[0013] Furthermore, a partition is provided on the wall of the feeding chamber, dividing the feeding chamber into a first feeding chamber and a second feeding chamber. The first feeding chamber is located above the second feeding chamber. The first feeding chamber is provided with the inlet, and the second feeding chamber is provided with the outlet. The partition is provided with a connecting channel, and the first feeding chamber and the second feeding chamber are connected through the connecting channel. The screw conveying mechanism includes a rotating shaft and a first screw blade, a second screw blade, and a material feeding component disposed on the rotating shaft. The first screw blade is located in the first feeding chamber, and the second screw blade is located in the second feeding chamber. When the first screw blade and the second screw blade rotate, they provide an upward conveying force to the material. The material feeding component is located in the second feeding chamber and is located on one side of the outlet.

[0014] Furthermore, the feeding member is rod-shaped and extends radially along the rotating shaft.

[0015] Furthermore, an inclined guide wall is provided on the side of the partition facing the feed inlet, the guide wall being used to guide the material to fall into the connecting channel.

[0016] Furthermore, the vibratory feeder also includes a feeder body and a vibration mechanism. The feeder body has a spiral channel, which is spiral and has an input position and an output position. The inlet section is disposed on the feeder body and is used to guide the material to the input position of the spiral channel. The outlet section is disposed on the feeder body and is used to receive the material coming out from the output position and guide the material to the weighing device. The vibration mechanism is disposed on the feeder body and the frame and is used to vibrate the feeder body.

[0017] Furthermore, the input position is located below the output position, the input position of the spiral channel is located in the middle of the disk body, and the output position of the spiral channel is located at the edge of the disk body.

[0018] Furthermore, the end of the outgoing segment away from the output position and the end of the incoming segment away from the input position intersect, and a feeding space for material to pass through is provided on one side of the intersection position.

[0019] Furthermore, the packaging equipment is a tea packaging equipment.

[0020] Unlike existing technologies, in the above technical solution, most of the material coming out of the discharge port of the feeding device falls into the feeding section of the weighing device, a small portion falls into the inlet section, and a small portion of the material slowly exits from the outlet section and enters the feeding section of the weighing device after being vibrated by the vibrating plate. When the weighing device detects that the material has reached the preset weight, the vibrating plate stops vibrating, thereby achieving accurate weighing. In this way, the design of the dispensing equipment is ingenious, which can quickly and quantitatively dispense materials with high efficiency. Attached Figure Description

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0064] Please see Figures 1 to 13 This embodiment of a packaging device includes:

[0065] Rack 7;

[0066] A feeding device is installed on the frame 7. The feeding device includes a hopper and a screw conveyor mechanism. The hopper includes a feeding chamber with a feeding port 13 and a discharging port 14. The screw conveyor mechanism is installed in the feeding chamber to guide the material to the discharging port 14.

[0067] The vibratory plate 5 is set on the frame 7 and is located below the discharge port 14. The vibratory plate 5 is provided with an inlet section 52 and an outlet section 53. The inlet section 52 is used to receive the material coming out of the discharge port 14.

[0068] The weighing device 6 is installed on the frame 7. The weighing device 6 is provided with a feeding section 611 and a discharging section 612. The feeding section 611 is located below the discharge port 14 and the discharge section 53. The feeding section 611 is used to receive the material coming out of the discharge port 14 and the discharge section 53. The discharging section 612 is used to output the weighed material.

[0069] Unlike existing technologies, in the above technical solution, most of the material coming out of the discharge port of the feeding device falls into the feeding section of the weighing device, a small portion falls into the inlet section, and a small portion of the material slowly exits from the outlet section and enters the feeding section of the weighing device after being vibrated by the vibrating plate. When the weighing device detects that the material has reached the preset weight, the vibrating plate stops vibrating, thereby achieving accurate weighing. In this way, the design of the dispensing equipment is ingenious, which can quickly and quantitatively dispense materials with high efficiency.

[0070] Please see Figure 10 , Figure 12 and Figure 13According to one embodiment of this application, the weighing device 6 includes a housing 61, a weight sensor 63, and an opening and closing mechanism 62. The housing 61 is provided with a connected feed section 611 and a discharge section 612, both of which are open for feeding and discharging materials. The weight sensor 63 is located at the bottom of the housing 61 and is used to detect the weight of the material. The opening and closing mechanism 62 is located on the housing 61 and between the feed section 611 and the discharge section 612, and is used for collecting or discharging materials. In the initial state, the opening and closing mechanism 62 blocks the channel between the feed section 611 and the discharge section 612. Material falls into the feed section 611 through the discharge port 14 of the feeding device or the guide section 53 of the vibrating plate 5. The material is blocked by the opening and closing mechanism 62. After the material reaches a preset weight, the opening and closing mechanism 62 opens, and the material is discharged through the discharge section 612.

[0071] Please see Figure 10 According to one embodiment of this application, the opening and closing mechanism 62 includes a motor 621, a cam 622, and an opening and closing gate 623. The opening and closing gate 623 is rotatably mounted on the outer wall of the housing 61 and located between the feeding section 611 and the discharging section 612. The opening and closing gate 623 is adapted to the channel between the feeding section 611 and the discharging section 612. Closing the opening and closing gate 623 can prevent material from moving towards the discharging section 612. A guide rod 624 is provided on the outer wall of the opening and closing gate 623. The guide rod 624 cooperates with the cam 622 and moves along the outer wall of the cam 622 to realize the opening or closing of the opening and closing gate 623. The motor 621 and the cam 622 are mounted on the outer wall of the housing 61 and are connected by a drive mechanism. The motor 621 drives the cam 622 to rotate. Cam 622 and guide rod 624 are slidably connected. Cam 622 rotates to push guide rod 624, which in turn causes opening and closing door 623 to rotate upwards, opening the channel between opening and closing door 623 and feeding section 611 and discharging section 612. Conversely, opening and closing door 623 rotates downwards, closing the channel between opening and closing door 623 and feeding section 611 and discharging section 612. It should be noted that opening and closing door 623 closes the channel between opening and closing door 623 and feeding section 611 and discharging section 612 under its own weight.

[0072] Please see Figure 11 Specifically, the cross-sectional shape of cam 622 is as follows: the bottom edge is a straight line, the top edge is an arc, and the left and right sides are also arcs. Taking the line connecting the midpoint of the bottom edge and the midpoint of the top edge as the center line, the cross-sectional shape of cam 622 is an axisymmetric figure. Cam 622 is eccentrically mounted on housing 61. It should be noted that if the bottom edge (straight line) is aligned with guide rod 624, cam 622 does not contact guide rod 624, thus keeping the door 623 closed.

[0073] According to one embodiment of this application, the opening and closing mechanism 62 further includes a proximity sensor, which is disposed on the cam 622 and the opening and closing door 623. The proximity sensor is used to detect the degree of proximity between itself and a detected component having a magnet or other magnetic material. Specifically, the proximity sensor includes a sensor body and a detected component. If the sensor body is disposed on the cam 622, the detected component is disposed on the opening and closing door 623; if the detected component is disposed on the cam 622, the sensor body is disposed on the opening and closing door 623. The controller determines the state of the opening and closing door 623. If the proximity sensor detects that the opening and closing door 623 is in a closed state, the controller controls the motor 621 to stop rotating; if the proximity sensor detects that the opening and closing door 623 is in an open state, the controller does not control the motor 621 to stop rotating.

[0074] Please see Figures 7 to 9 According to one embodiment of this application, the vibratory feeder 5 further includes a disc body 51 and a vibration mechanism 54. The disc body 51 is provided with a spiral channel 511, which is spiral and is provided with an input position 512 and an output position 513. An inlet section is provided on the disc body 51 for receiving material from the feeding device and guiding the material to the input position 512. An outlet section 53 is provided on the disc body 51 for receiving material from the output position 513 and guiding the material to the weighing device 6. The vibration mechanism 54 is provided on the disc body 51 and the frame 7 for vibrating the disc body 51 so that the material moves along the inlet section 52, the spiral channel 511, and the outlet section 53.

[0075] Please see Figures 7 to 9 According to one embodiment of this application, the input position 512 is located below the output position 513, with the input position 512 at a lower position and the output position 513 at a higher position. The spiral channel 511 spirals upwards, and under the vibration of the vibrating plate 5, the material gradually moves towards the output position 513, achieving precise discharge. In some embodiments, the input position 512 is located above the output position 513, with the input position 512 at a higher position and the output position 513 at a lower position. This results in a faster discharge speed and a slightly larger quantity, which may lead to excessive discharge.

[0076] Please see Figure 7 and Figure 8 According to one embodiment of this application, the input position 512 of the spiral channel 511 is located in the middle of the disk body 51, and the output position 513 of the spiral channel 511 is located at the edge of the disk body 51.

[0077] According to one embodiment of this application, the inlet section 52 is disposed on the outer wall of the disc body 51, and extends upward to directly above the input position 512. It should be noted that the inlet section 52 may not be in contact with the input position 512. When the input position 512 of the spiral channel 511 is located in the middle of the disc body 51, the inlet section 52 spans across the top of the disc body 51. A support rod can be provided to support the inlet section 52. The support rod can stand on the spiral channel 511 or the disc body 51, provided that the support rod does not affect the movement of the material.

[0078] Please see Figures 7 to 9 According to one embodiment of this application, a step 531 is formed at the connection between the output segment 53 and the output position 513. The output segment 53 is located below the output position 513. The output segment 53 is located at a low position, and the output position 513 is located at a high position, so that the material will not be returned after falling into the output segment 53.

[0079] Please see Figure 8 and Figure 12 According to one embodiment of this application, the output section 53 is disposed on the outer wall of the disc body 51. The end of the output section 53 away from the output position 513 and the end of the inlet section 52 away from the input position 512 intersect. A material drop space 8 is provided on one side of the intersection for material to pass through. That is, the end of the output section 53 away from the output position 513, the end of the inlet section 52 away from the input position 512, and the material drop space 8 intersect. The discharge port 14 of the feeding device is provided above the intersection, and the feeding part 611 of the weighing device 6 is provided below the intersection. In this way, most of the material coming out of the discharge port 14 of the feeding device falls into the feeding part 611 of the weighing device 6, and a small part falls onto the inlet section 52. The small part of the material slowly enters the feeding part 611 of the weighing device 6 from the output section 53 after being vibrated by the vibrating plate 5. When the weighing device 6 detects that the material has reached the preset weight, the vibrating plate 5 stops vibrating, thereby achieving accurate weighing.

[0080] Please see Figure 12 To dispense 150 grams of material, more than 150 grams of material is fed into the inlet 13. Approximately 140 grams of material falls into the feed section 611 through the outlet 14. The remaining material (weighing much less than 140 grams, approximately 15 grams) falls onto the inlet section 52. The vibrator 541 controls the disc 51 to vibrate, causing the material to gradually move upward along the spiral channel 511 to the output position 513. During the vibration process, the material gradually falls into the feed section 611 through the outlet section 53. The weight sensor 63 detects the weight of the material in the housing 61 in real time. When the material reaches 150 grams, the weight sensor 63 sends a command to the controller, which then controls the vibrator 541 and the motor 621 to stop working, achieving precise material dispensing.

[0081] Please see Figure 9According to one embodiment of this application, the vibration mechanism 54 includes a vibrator 541 and a fixed base 542. The top of the vibrator 541 is disposed on the bottom of the disc body 51, and the bottom is disposed on the fixed base 542. The working part of the vibrator 541 is a rod-shaped hollow cylinder with an eccentric oscillator inside. It rotates at high speed under the drive of a motor to generate high-frequency micro-amplitude vibration, thereby driving the vibrating disc 5 and the material to vibrate.

[0082] Please see Figure 7 and Figure 8 According to one embodiment of this application, the top of the vibrator 541 and the bottom of the disc 51 are locked together by several bolts. A fixing rod is also provided at the center of the top of the vibrator 541, and the fixing rod passes through the center of the bottom of the disc 51 to prevent the disc 51 from shifting.

[0083] According to one embodiment of this application, the vibratory feeder 5, the feeding device, and the weighing device 6 are all connected to a controller, which is responsible for process management. Specifically, the vibrator 541 of the vibratory feeder is electrically connected to the controller, and the controller controls the operation of the vibrator 541; the power source 25 of the screw conveyor mechanism 2 in the feeding device is electrically connected to the controller, and the controller controls the operation of the power source 25; the weight sensor 63 and the motor 621 of the weighing device 6 are both electrically connected to the controller, and the controller controls the operation of the weight sensor 63 and the motor 621.

[0084] Please see Figures 7 to 9 According to one embodiment of this application, the spiral channel 511, the inlet section 52, and the outlet section 53 have sidewalls on their left and right sides to define the material movement path. The side of the spiral channel 511, the inlet section 52, and the outlet section 53 that is to discharge material is open. For example, the side of the inlet section 52 located directly above the disc 51 facing the input position 512 is open, so that material can fall into the spiral channel 511.

[0085] Please see Figures 7 to 9 According to one embodiment of this application, the disk body 51 is disc-shaped.

[0086] Please see Figures 1 to 6According to one embodiment of this application, a partition 15 is provided on the wall of the feeding chamber, dividing the feeding chamber into a first feeding chamber 11 and a second feeding chamber 12. The first feeding chamber 11 is located above the second feeding chamber 12, and the first feeding chamber 11 is provided with an inlet 13, while the second feeding chamber 12 is provided with an outlet 14. The partition 15 is provided with a connecting channel 17. The first feeding chamber 11 and the second feeding chamber 12 are connected by the connecting channel 17. The screw conveying mechanism 2 includes a rotating shaft 24 and a first screw blade 21, a second screw blade 22, and a material feeding element 23 disposed on the rotating shaft 24. The first screw blade 21 is located in the first feeding chamber 11, and the second screw blade 22 is located in the second feeding chamber 12. When the first screw blade 21 and the second screw blade 22 rotate, they provide an upward conveying force to the material. The material feeding element 23 is located in the second feeding chamber and is located on one side of the outlet 14.

[0087] Both the first helical blade 21 and the second helical blade 22 are helical and rotate around the axis of the shaft 24. The first helical blade 21 and the second helical blade 22 can be segmented or continuous—the first helical blade 21 and the second helix are connected end to end.

[0088] The partition divides the feeding chamber into two parts—a first feeding chamber and a second feeding chamber. Material enters the first feeding chamber through the inlet and then gradually enters the second feeding chamber through the connecting channel. During this process, the first spiral blade provides an upward conveying force to the material in the first feeding chamber, lifting and loosening it to slow the material's entry into the second feeding chamber. The second spiral blade provides an upward conveying force to the material entering the second feeding chamber, lifting and loosening it to prevent material accumulation at the bottom of the second feeding chamber. The feeding device and the discharge port are positioned opposite each other, allowing the feeding device to push the material towards the outer discharge port as it rotates with the shaft, ensuring timely feeding. By setting up the partition, the material discharge speed is slowed down, and the feeding device is prevented or reduced from agitating or damaging the material inside the feeding chamber.

[0089] Please see Figure 1 and Figure 3 According to one embodiment of this application, the feeder 23 is rod-shaped and extends radially along the rotating shaft 24. In some embodiments, the feeder 23 is plate-shaped, ring-shaped, etc.

[0090] According to one embodiment of this application, there are multiple material guides 23, which are evenly distributed along the circumference of the rotating shaft 24.

The output shaft of the motor is connected to the lower end of the rotating shaft 24. The output shaft of the motor and the rotating shaft 24 can be assembled via a coupling. Notably, the output shaft of the motor and the rotating shaft 24 can be connected via a gearbox, which serves to increase or decrease speed, facilitating the spiral conveying mechanism 2 to reach a preset speed. In some embodiments, the power source 25 is an internal combustion engine. An internal combustion engine is a type of power machinery that converts the heat energy released by burning fuel inside the machine into power directly.

[0095] Please see Figure 2 According to one embodiment of this application, the rotating shaft 24 passes through the communicating channel 17. In some embodiments, the partition 15 is provided with a hole for receiving the rotating shaft 24.

[0097] Please see Figure 5 and Figure 6 According to one embodiment of this application, in order to guide the material to the next process, the double-layer feeding device further includes a guide chute 4. The guide chute 4 is disposed on the hopper 1, the inlet of the guide chute 4 is connected to the outlet 14, and the outlet of the guide chute 4 guides the material in another direction.

[0098] According to one embodiment of this application, the double-layer feeding device further includes a controller for managing the process flow. The power source 25 of the screw conveyor 2 is electrically connected to the controller, which controls the operation of the power source 25, thereby causing the rotating shaft 24 to rotate.

[0099] Please see Figure 4 According to one embodiment of this application, the double-layer feeding device further includes a discharge adjustment mechanism 3, which is disposed on the hopper and is used to control the opening degree of the discharge port 14. If the discharge adjustment mechanism 3 controls the opening degree of the discharge port 14 to be larger, more material will be discharged; if the discharge adjustment mechanism 3 controls the opening degree of the discharge port 14 to be smaller, less material will be discharged.

[0100] Please see Figure 4 , Figure 5 and Figure 6According to one embodiment of this application, the discharge adjustment mechanism includes a rotating disk 31 and a baffle plate 32. The discharge port 14 is located at the bottom and side wall of the second feeding chamber 12. The rotating disk 31 is rotatably disposed on the bottom of the second feeding chamber 12 and is used to control the opening degree of the portion of the discharge port 14 at the bottom of the second feeding chamber 12. The opening degree of the portion of the discharge port 14 at the bottom of the second feeding chamber 12 is adjusted by rotating the rotating disk 31. The rotation direction of the rotating disk 31 is along its own circumferential direction. If the opening degree of the portion of the discharge port 14 at the bottom of the second feeding chamber 12 is larger, more material is discharged; if the opening degree of the portion of the discharge port 14 at the bottom of the second feeding chamber 12 is smaller, less material is discharged. Specifically, a groove is provided on the bottom of the second feeding chamber 12, and the rotating disk 31 is slidably connected in the groove. The rotation of the rotating disk 31 in the groove is controlled manually. A baffle plate 32 is detachably mounted on the side wall of the second feeding chamber 12 to control the opening degree of the portion of the discharge port 14 on the side wall of the second feeding chamber 12. By mounting the baffle plate 32 at different positions on the side wall of the second feeding chamber, the opening degree of the portion of the discharge port 14 on the side wall of the second feeding chamber 12 can be adjusted. A larger opening degree of the portion of the discharge port 14 on the side wall of the second feeding chamber 12 results in more material being discharged, while a smaller opening degree of the portion of the discharge port 14 on the side wall of the second feeding chamber 12 results in less material being discharged. Specifically, the baffle plate 32 and the second feeding chamber 12 are provided with threaded holes for bolts to be screwed into. Bolts are screwed into the threaded holes of the baffle plate 32 and the second feeding chamber 12 to achieve quick installation. In some embodiments, the baffle plate 32 and the second feeding chamber 12 can be quickly installed together by magnetic attraction.
